Internal Revenue Code
What changed between versions
The reference date for the Internal Revenue Code was changed from January 1, 2025 to January 1, 2026, meaning state tax calculations will lag federal changes by one year rather than adopting them immediately.
The expiration date for the emergency rulemaking authority was added, set to expire on July 1, 2027.
New provisions require taxpayers to add back 100% of certain federal deductions, such as bonus depreciation and business interest expenses, to their Florida taxable income for years beginning after 2025.
The bill now mandates that taxpayers reverse the effects of specific federal tax changes (like the creation of Section 174A for R&D expenses) by adding back the deducted amounts to state taxable income.
A new subsection was added to the definitions section to clarify that federal amendments affecting taxable income for years before 2026 cannot be applied retroactively.
